Returns true if the character is classified as punctuation, false otherwise.
template< class charT >
bool ispunct( charT ch, const std::locale& loc ) {
return std::use_facet<std::ctype<charT>>(loc).is(std::ctype_base::punct, ch);
} |
Demonstrates the use of ispunct() with different locales (OS-specific).
#include <iostream>
#include <locale>
int main()
{
const wchar_t c = L'\u214b'; // upside-down ampersand
std::locale loc1("C");
std::cout << "ispunct('⅋', C locale) returned "
<< std::boolalpha << std::ispunct(c, loc1) << '\n';
std::locale loc2("en_US.UTF-8");
std::cout << "ispunct('⅋', Unicode locale) returned "
<< std::boolalpha << std::ispunct(c, loc2) << '\n';
}Output:
isalpha('⅋', C locale) returned false
isalpha('⅋', Unicode locale) returned true| checks if a character is a punctuation character (function) |
|
| checks if a wide character is a punctuation character (function) |
